I want to scan all the files in a directory. Find the ones that have been modified since I last run the program.

opendir, readdir for reading a single directory, File::Find to read recursively. Calculate a checksum with e.g. Digest::MD5 and store filenames and checksum in a database, probably a self-contained like DBI::SQLite.

Present them on a web page.

Select a subset of them. Save the subset to a database.

Copy the subset to across to another directory.

File::Copy

TIMTOWDI - these are just the apples I can think of that hang lowest, and are easiest to pick.
